Title: Heat treatment of hydrocarbon residues
IPC: C10G9/42
Filed: 1939-01-23
Abstract: 524,116. Distilling and coking hydrocarbons. HOUDRY PROCESS CORPORATION, and HOUDRY, E. J. Jan. 23, 1939, No. 2271. [Class 32] Heavy hydrocarbons, e.g. tarry and asphaltic bottoms and residues are converted to vapours and coke by heating them without substantial cracking and passing them into the lower, reduced end of a coking zone through which they pass upwardly, the heavy liquid components being maintained by agitation in the vapours formed until they are reduced to coke. Inert gases, e.g. steam may be employed to aid the vaporisation. Heavy hydrocarbons preferably mixed with steam are passed quickly to minimise cracking through a tube still 5 heated to 850-930‹F. into the bottom of one or more separators 8 additional steam being added through a valved line 7 the charge entering through a reduced lower portion 8a leading to an expansion chamber 8b with tapering walls where solids separate out. Vapours pass off through a line 9 to a chamber 10 where they may be subjected to vapour phase catalytic treatment. Two separators 8 are preferably used alternately and when one is filled with coke it is (a) purged of volatiles by passing in steam through line 7 or by vacuum purging (b) freed from coke by lowering and rotating a scraper 11 the loosened deposits being then blown out by gaseous agent into a receptacle 16. Vanadium, silica, tin, lead, cobalt, magnesium, iron, aluminium, titanium, sodium, gold may be recovered from cokes thus formed from Mexican and South American crudes.

Abstract: 478,397. Making laminated boards. DOLLKEN & CO., GES., W. Jan. 27, 1937, No. 2442. Convention date, Jan. 27, 1936. [Classes 145 (i) and 145 (ii)] The cores of laminated panels or boards consist of wood strips a connected by fillets t inserted in grooves in their end faces whilst the strips are passed together side by side. In an apparatus for making the cores, the strips are fed on to rails c from a container b by hooks e on a conveyer chain d, a spring- pressed plate g holding the strips down. Whilst being so fed the strips pass circular saws h, i which respectively out them to length and form the grooves in their end faces. When sufficient strips for a panel have been fed, a counter l operated by their passage stops the feeding mechanism, the strips having moved forward to rails k which engage the grooves in their ends. A carriage carrying a clamping device is then moved forward on rails m, the strips being supported on it by bars n and clamped together by members p pivotally mounted on spindles o operated by handwheels v to retract the members after they have been turned down to engage the end strip. The carriage is moved back to the position shown, quick-drying glue being introduced into the grooves of the strips during the movement by automatic devices r, and the fillets are then inserted. In the case of long strips glue may be supplied at one or more points between them by an automatic device s. The fillets may be moistened with formaldehyde solution so that the glue will dry quickly.
